Distribution and remarks.--Gaius cooperi (formerly known by WAM identification code 'MYG063') is a large species with a widespread distribution in the Mallee and surrounding bioregions of southern Western Australia, from Collie, Tenterden and Albany in the west, north to Voyager Quarry and Holleton, and east to McDermid Rock and Pyramid Lake (Fig.
2) is located in Gamilaraay Aboriginal Country in the NSW section of the Brigalow Belt South bioregion. Most native vegetation on more productive soils in the surrounding area has been cleared for agriculture, with the Pilliga Forest left as a very large remnant on the poorest sandy soils.
Syllophopsis sechellensis is now known from 6 of the 7 terrestrial bioregions where ants occur: Afrotropics, Indomalaya, Australasia, Oceania, Palearctic, and Neotropics.
However, our results indicated that biologically they could be treated as two bioregions. The SB region often exhibited higher richness numbers, for all macroinvertebrate groups, but notably for Trichoptera (33 genera in SB region, 20 in SO region) and Ephemeroptera (24 genera in SB region, 16 in SO region).
Geomorphological surveys of reef development in Western Australia suggest that reefs in the Kimberley coastal bioregion are uniquely characterized by the development of Holocene accretionary veneers of coral-algal limestone (>12,000 years old) on a Proterozoic basement (2,500-543 million years old) [1].
Eight of the state's 10 bioregions contain forests or rangelands, as defined by the California Department of Forestry and Fire Protection (CDFFP, now known as Cal Fire) for natural resources assessment purposes.
These units represent key California bioregions, ranging from the mountains to coasts to deserts.
Additionally, three European bioregions were analysed in the first round to obtain indicative data which might be useful in designing the concept of a 'bioregion', a term being rather vaguely used in the cluster discussion so far.
Sampling sites were representative of a variety of habitats and climates, which can be simplified into 5 different bioregions (Figure) (12).
It showed, with more detail than anyone but a dedicated geographer could possibly absorb, how the ecology of a place determined the kinds of lives and livelihoods its denizens would have and thus how people could properly live in self-regarding and self-determined bioregions without the interference of large and centralized governments that always try to homogenize diverse geographical areas.
A resilient city, on the other hand, would be more adaptable to change, and more in balance with its bioregions and the biosphere as a whole.
